Antimicrobial Resistance in Escherichia coli

Poirel, Laurent ; Madec, Jean-Yves ; Lupo, Agnese ; Schink, Anne-Kathrin ; Kieffer, Nicolas ; Nordmann, Patrice ; Schwarz, Stefan

In: Microbiology Spectrum, 2018, vol. 6, no. 4, p. -

Multidrug resistance in Escherichia coli has become a worrying issue that is increasingly observed in human but also in veterinary medicine worldwide. E. coli is intrinsically susceptible to almost all clinically relevant antimicrobial agents, but this bacterial species has a great capacity to accumulate resistance genes, mostly through horizontal gene transfer. The most problematic...

Global glacier volume projections under high-end climate change scenarios

Shannon, Sarah ; Smith, Robin ; Wiltshire, Andy ; Payne, Tony ; Huss, Matthias ; Betts, Richard ; Caesar, John ; Koutroulis, Aris ; Jones, Darren ; Harrison, Stephan

In: The Cryosphere, 2019, vol. 13, no. 1, p. 325–350

The Paris agreement aims to hold global warming to well below 2 ∘C and to pursue efforts to limit it to 1.5 ∘C relative to the pre-industrial period. Recent estimates based on population growth and intended carbon emissions from participant countries suggest global warming may exceed this ambitious target. Here we present glacier volume projections for the end of this century, under a...

Surviving in the BRICS: the struggle of South African business in coping with new partners and investors

Wenzel, Nadine ; Freund, Bill ; Graefe, Olivier

In: International Review of Applied Economics, 2019, vol. 33, no. 1, p. 51–70

The purpose of this paper is to improve our understanding of how South African economic actors react to the gradual entry of non-South African BRICS firms in their established business areas. Throughout the twentieth century, South Africa’s trade and investment activities were conducted overwhelmingly with Western countries. However, the end of apartheid coincided with significant shifts as...

A novel approach to estimate glacier mass balance in the Tien Shan and Pamir based on transient snowline observations

Barandun, Martina ; Huss, Matthias (Dir.)

Thèse de doctorat : Université de Fribourg, 2018 ; no 2099.

Glaciers are recognised as an excellent proxy for climate change and their centennial massloss has accelerated during the past decades. The Central Asian mountain ranges Tien Shan and Pamir host over 25,000 glaciers that have been observed to respond heterogeneous to climate change. Glacier changes in the region have very important consequences on the water availability for the densely populated...

Time- and angle-resolved photoemission spectroscopy of solids in the extreme ultraviolet at 500 kHz repetition rate

Puppin, M. ; Deng, Y. ; Nicholson, C. W. ; Feldl, J. ; Schröter, N. B. M. ; Vita, H. ; Kirchmann, P. S. ; Monney, Claude ; Rettig, L. ; Wolf, M. ; Ernstorfer, R.

In: Review of Scientific Instruments, 2019, vol. 90, no. 2, p. 023104

Time- and angle-resolved photoemission spectroscopy (trARPES) employing a 500 kHz extreme-ultraviolet light source operating at 21.7 eV probe photon energy is reported. Based on a high-power ytterbium laser, optical parametric chirped pulse amplification, and ultraviolet-driven high-harmonic generation, the light source produces an isolated high-harmonic with 110 meV bandwidth and a flux of...

Dopamine transporter (DAT) knockdown in the nucleus accumbens improves anxiety- and depression-related behaviors in adult mice

Bahi, Amine ; Dreyer, Jean-Luc

In: Behavioural Brain Research, 2019, vol. 359, p. 104–115

Many epidemiological and clinical studies have demonstrated a strong comorbidity between anxiety and depression, and a number of experimental studies indicates that the dopamine transporter (DAT) is involved in the pathophysiology of anxiety and depression. However, studies using laboratory animals have yielded inconclusive results. The aim of the present study was to examine the effects of...

Spatial transformation abilities and their relation to later mathematics performance

Frick, Andrea

In: Psychological Research, 2018, p. 1-20

Using a longitudinal approach, this study investigated the relational structure of different spatial transformation skills at kindergarten age, and how these spatial skills relate to children’s later mathematics performance. Children were tested at three time points, in kindergarten, first grade, and second grade (N = 119). Exploratory factor analyses revealed two subcomponents of spatial...

Cervantes y los pueblos del norte: un acercamiento imagológico

Sánchez Jiménez, Antonio

In: Atalanta, 2018, vol. 6, p. 129-147

El análisis imagológico de los estereotipos nacionales presentes en el Persiles llama la atención sobre la peculiaridad de los personajes de Antonio y su familia, los «españoles bárbaros». Este trabajo postula que su barbarie no procede del contagio de los habitantes de la isla Bárbara ni se circunscribe a este espacio septentrional, sino que más bien se relaciona con la imagen...

A martyr factory? Roman Catholic crusade, Protestant missions and anti-communist propaganda against Soviet anti-religious policies, 1929-37

Roulin, Stéphanie

In: Twentieth Century Communism, 2014, vol. 7, no. 7, p. 153-173

The renewed outbreak of anti-religious measures in the USSR in 1929 aroused reactions of protest in Europe in which it was the Catholic Church who set the tone. In a comparative perspective (addressing the Catholic and Protestant churches in Europe), the article presents the main protest initiatives that were in play leading up to the publication of the Encyclical Letter Divini Redemptoris...
